Description

Dispensing device
Technical Field
The present invention relates to a device for separating powder such as cement raw material discharged from a cyclone preheater of a cement sintering apparatus.
Background
The cement sintering apparatus includes a preheater, a pre-firing furnace, a cement kiln, and a clinker cooler, and cement clinker is produced by preheating a cement raw material supplied to the preheater by a cyclone preheater having a multi-stage structure, pre-firing the cement raw material in the pre-firing furnace, and then sintering the cement raw material in the cement kiln. Then, the cement clinker is cooled by a clinker cooler and conveyed to a cement grinding process.
In the cyclone preheater, the cement raw material is preheated while gradually moving from the cyclone above to the cyclone below, and for the purpose of preventing the cement manufacturing facility from forming a cover (see patent document 1) or recovering mercury in the exhaust gas of the cement kiln (see patent document 2), a part of the cement raw material may be taken out from the outlet chute of the cyclone and used.

Disclosure of Invention
Problems to be solved by the invention
In the case where a part of the cement raw material falling into the outlet chute of the cyclone preheater is agglomerated into a lump, the distributor may be damaged or the lump may not be received, and the desired distribution may not be performed.
Further, since the cement raw material falling down in the chute has very high fluidity, the cement raw material may be flushed through the distributor and the amount of the cement raw material exceeding a desired amount may be distributed.
Further, since the cement raw material in the chute does not fall down in a fixed path, the distributor may not receive the cement raw material and the desired distribution may not be performed.
Accordingly, the present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to provide an apparatus capable of stably collecting powder such as a cement raw material with a simple structure.
Means for solving the problems
In order to achieve the above object, a dispensing device according to the present invention is a dispensing device for dispensing a part of powder falling in a chute, the dispensing device including: a screw conveyor that penetrates the chute, and a part of the housing is opened inside the chute, and receives a part of the powder from the opening; and a collision separation member that is provided above the screw conveyor in the chute, and that collides with an object having a predetermined size or more when the object falls down, thereby preventing the object from directly flowing into the screw conveyor and being clogged therewith.
According to the present invention, even when a part of powder falling down in the chute, such as cement raw material, is agglomerated and becomes a lump, the lump can be crushed or separated by the collision separation member, and therefore, clogging or breakage of the screw conveyor can be prevented, and desired separation can be performed.
In the above dispensing device, the rotation shaft of the screw conveyor may be inclined in a range of 5 ° or more and 20 ° or less with respect to a horizontal plane such that the end portion on the discharge port side of the screw conveyor is located above the other end portion. Thus, even if the powder passes between the inner wall of the screw conveyor and the screw due to the rush current, the powder passing through can be returned to the receiving side of the screw conveyor, and therefore, the powder in an amount exceeding a desired amount can be prevented from being sorted out.
In the above-described powder dispensing device, a guide member that guides the powder falling in the chute in the direction of the opening of the screw conveyor can be provided, and thus a desired amount of powder can be stably dispensed.
In the above-described dispensing device, if the rotating shaft of the screw conveyor is configured to be capable of changing the rotation speed, the dispensing amount of the powder can be easily controlled.
In the above dispensing device, the cooling water passage is formed inside the rotary shaft of the screw conveyor, and the mechanism for supplying the cooling water to the cooling water passage is provided outside the chute, whereby the powder can be dispensed while preventing the screw from being damaged in a high-temperature environment.
Effects of the invention
As described above, according to the dispensing device of the present invention, the powder such as the cement raw material can be stably dispensed with a simple structure.

Detailed Description
Next, an embodiment for carrying out the present invention will be described in detail with reference to fig. 1 to 3. In the following, a case will be described as an example where the separation device of the present invention is used for separating a cement raw material (hereinafter, simply referred to as "raw material") discharged from a cyclone preheater of a cement burning apparatus.
The dispensing device 1 of the present invention includes: a raw material outlet portion 10a of a cyclone 10 of a preheater (for example, a cyclone of a third stage from below), a main body (chute) 2 connected between the cyclone 10 and a raw material chute 11, a guide plate 3 penetrating an upper portion 2a of the main body 2 obliquely downward, an impact separation rod 4 penetrating the main body 2 in a horizontal direction below the guide plate 3, a screw conveyor 5 penetrating the main body 2 obliquely below the impact separation rod 4 and held by a holding member 6, and the like. Note that, for simplification of the drawing, the description of the screw conveyor 5 is omitted in fig. 2, and a state in which the screw conveyor 5 is horizontally arranged is shown in fig. 3.
The main body 2 is connected between the raw material outlet 10a of the cyclone 10 and the raw material chute 11 via a flange 7, and is composed of a square cylindrical upper part 2a located immediately below the raw material outlet 10a and a circular lower part 2b located immediately above the cylindrical raw material chute 11. A cleaning port 8 and a pressure measurement port 9 are formed in the uppermost portion of the upper portion 2 a. The cleaning port 8 is openable and closable, the cleaning port 8 is used when the raw material R is stuck to the inner wall of the main body 2 or the screw conveyor 5, and the pressure gauge 12 is inserted into the pressure measurement port 9. A refractory 2c is applied to the inner wall of the body 2.
The guide plate 3 is formed in a rectangular plate shape, and as shown in fig. 3, two pieces of the guide plate 3 are provided so as to penetrate the uppermost portion of the upper portion 2a of the main body 2 from the left and right so that an angle θ 1 with the axis L of the upper portion 2a of the main body 2 is 40 ° or less, and the raw material R falling from the raw material outlet portion 10a is guided in the direction of the screw conveyor 5 penetrating the upper portion 2a of the main body 2. The guide plate 3 is supported by the main body 2 so that the insertion length of the guide plate 3 into the main body 2 can be adjusted, and when the raw material R falling from the raw material outlet port 10a can be guided to the receiving port 5b of the screw conveyor 5 even if the guide plate 3 is not present, the guide plate 3 is not necessary.
The collision and separation rods 4 are circular in cross section, 5 collision and separation rods 4 are provided so as to penetrate the center portion of the upper portion 2a of the body 2 in the horizontal direction, and are arranged in a mountain shape so as to be bilaterally symmetrical about the center collision and separation rod 4 as shown in fig. 2 and 3. The collision separation rod 4 crushes the large pieces falling from the raw material outlet portion 10a to prevent the large pieces from directly falling onto the screw conveyor 5, thereby preventing the screw conveyor 5 from being damaged. The collision and separation rods 4 are supported by the body 2 so as to be insertable and removable, and the number of the collision and separation rods 4 to be inserted can be changed.
The screw conveyor 5 includes a cylindrical housing 5a having a receiving port 5b and a discharge port 5c, a rotary shaft 5d, a screw 5e fixed to the rotary shaft 5d, a motor 5g capable of adjusting the rotation speed of the rotary shaft 5d, and a cooling water passage 5f extending over the entire length of the rotary shaft 5d and provided inside the rotary shaft 5 d. The receiving opening 5b is formed as an opening excluding the upper half of the housing 5 a. The rotation shaft 5d of the screw conveyor 5 is inclined in a range of 5 ° to 20 ° (angle θ 2) with respect to the horizontal plane H so that the end of the discharge port side 5c is located above the other end.
Next, the operation of the dispensing device 1 having the above-described configuration will be described with reference to fig. 1.
A part of the raw material R falling from the raw material outlet 10a of the cyclone 10 of the preheater is guided to the inlet 5b of the screw conveyor 5 directly or after being pulverized by the guide plate 3 and the collision separation rod 4 penetrating the main body 2 of the fractionating apparatus 1, and enters the casing 5 a. The raw material R that has entered the casing 5a is accommodated in a space formed between the inner wall of the casing 5a and the screw 5e, moves to the left by the rotation of the screw 5e, and is finally discharged from the discharge port 5c to the side of the distribution chute 13. The raw material R not separated by the separator 1 is supplied from the raw material chute 11 to the cyclone or the like below.
Since the raw material R has a small particle diameter and extremely high fluidity, the raw material R may pass between the inner wall of the casing 5a of the screw conveyor 5 and the screw 5e and rapidly move toward the discharge port 5c side in the casing 5 a. However, since the screw conveyor 5 is inclined so that the discharge port 5c side is directed upward as described above, the raw material R is prevented from rapidly moving toward the discharge port 5c side of the casing 5a, and a larger amount of the raw material R than a desired amount is prevented from being discharged from the discharge port 5 c.
The amount of the divided raw material R is adjusted by adjusting the position of the guide plate 3 or adjusting the rotation speed of the motor 5g of the screw conveyor 5, that is, the rotation speed of the rotating shaft 5 d.
When the temperature inside the main body 2 is high, the cooling water is flowed from the outside of the main body 2 to the cooling water passage 5f of the rotary shaft 5d to protect the rotary shaft 5 d.
In addition, since the dispensing device 1 can connect the main body 2 to the raw material outlet 10a of the cyclone 10 and the raw material chute 11 via the flange 7, it can be easily installed in an existing facility. Further, the entire dispensing device 1 can be removed by removing the main body 2 from the raw material outlet portion 10a and the raw material chute 11 via the flange 7 and removing the dispensing chute 13 from the discharge port 5c, and thus maintenance can be easily performed.
In the above embodiment, the guide plates 3 are provided in the form of 2 rectangular plates, but the shape and number of the guide plates 3 and the angle θ 1 with the axis L of the upper portion 2a of the main body 2 can be changed as appropriate depending on the installation place of the dispensing device 1, the flow direction of the raw material R, and the like.
Further, the collision separation rod 4 is not limited to a circular cross section, and may be a rectangular cross section, and the number of the collision separation rods and the positions thereof may be changed as appropriate. The collision separation rod 4 may not be rod-shaped, and may be formed in a plate shape having an opening, for example, as long as it can crush the large pieces falling from the raw material outlet portion 10a, prevent the screw conveyor 5 from being damaged, and do not interfere with the flow of the raw material R to the screw conveyor 5.
Further, although the case of separating the cement raw material discharged from the cyclone preheater of the cement burning apparatus has been exemplified, the separation apparatus of the present invention is not limited to such a cement raw material, and may be applied to any powder falling in the chute, and can be preferably used particularly for a powder having a large fluidity and easily aggregated into large lumps.
